DETAILED DESCRIPTION

[0036] The invention is further described below with reference to the accompanying drawings and specific embodiments:

[0037] Example:

[0038] Reference Figure 1 - Figure 9 The present invention discloses an electromagnetic measuring device for preventing leakage of electric current in electronic and electrical equipment, comprising an electromagnetic detection meter 1, a clamping plate 2 being fixedly mounted at the bottom end of the electromagnetic detection meter 1, a transverse sliding frame 3 being provided inside the clamping plate 2, and a longitudinal guide rail structure 4 being provided inside the transverse sliding frame 3;

[0039] The clamping plate 2 includes a bottom plate 21, which is fixedly connected to the bottom end of the electromagnetic detection meter 1. Guide plates 22 are provided on both sides of the bottom plate 21, and a mounting platform 23 is provided on the end sides of the two guide plates 22.

[0040] The transverse sliding frame 3 includes a fixing plate 31, which is installed between the two guide plates 22 and fixedly connected to the mounting platform 23. The end of the fixing plate 31 away from the mounting platform 23 is rotatably connected to a transverse scale plate 32, and a transverse sliding groove 33 is provided inside the transverse scale plate 32;

[0041] The longitudinal guide rail structure 4 includes a transverse slider 41, which is slidably arranged inside the transverse slide groove 33. A first sliding component 6 is provided at both ends of the transverse slider 41. The bottom end of the transverse slider 41 is hinged with a longitudinal scale plate 43 through a connecting hinge 42. A longitudinal slide groove 44 is provided inside the longitudinal scale plate 43. An electromagnetic sensor 5 is slidably arranged inside the longitudinal slide groove 44. A second sliding component 7 is provided at the bottom end of the electromagnetic sensor 5, wherein the electromagnetic sensor 5 is connected to the electromagnetic detection meter 1 through a wire.

[0042] In this embodiment, when in use, the electrician holds the handles provided on both sides of the electromagnetic detection meter 1 and makes the display screen of the electromagnetic detection meter 1 face himself, and then rotates the longitudinal scale plate 43 along the connecting hinge 42 so that the longitudinal scale plate 43 forms a right angle with the transverse scale plate 32, as shown in FIG. Figure 6 As shown, the horizontal scale plate 32 is rotated along the hinge with the fixed plate 31 so that the horizontal scale plate 32 and the bottom plate 21 are perpendicular to each other, as shown in FIG. Figure 7 As shown, when the electrician holds the electromagnetic detection meter 1, the bottom end of the electromagnetic detection meter 1 has a bracket of a certain length, so that the electromagnetic sensor 5 can be close to the ground when the electrician is standing upright, which can avoid the electrician bending over to detect the leakage, thereby improving the comfort during detection;

[0043] When the leakage point is detected, the horizontal scale plate 32 is rotated to be flush with the bottom plate 21. Figure 6 As shown, at this time, the horizontal scale plate 32 is perpendicular to the vertical scale plate 43, and the electromagnetic detection meter 1 is attached near the leakage point, and the vertical scale plate 43 and the second sliding component 7 are gradually slid until the value of the electromagnetic sensor 5 reaches the maximum value. At this time, the electromagnetic sensor 5 corresponds to the leakage point. Specifically, since the leakage point will generate an electromagnetic field, the closer the position is to the electromagnetic field, the larger the reading of the electromagnetic sensor 5 is. Therefore, when the value of the electromagnetic sensor 5 is the maximum value, the position of the electromagnetic sensor 5 corresponds to the leakage point.

[0044] Coordinates are formed by the horizontal scale plate 32 and the vertical scale plate 43, and the electromagnetic sensor 5 forms accurate coordinate points through the slidable vertical scale plate 43 and the second sliding component 7, which can effectively improve the accuracy of leakage detection and facilitate maintenance of the leakage.

[0045] In a further preferred embodiment of the present invention, Figure 7 As shown, a positioning protrusion 24 is provided on one end of the inner side of the guide plate 22 close to the mounting platform 23 , and a rubber pad 25 is fixedly provided on the end of the positioning protrusion 24 .

[0046] In this embodiment, by providing the positioning protrusions 24 and the rubber pads 25, the horizontal scale plate 32 is rotated along the hinge with the fixing plate 31 until the side wall of the horizontal scale plate 32 contacts the rubber pads 25, so as to facilitate positioning of the horizontal scale plate 32, so as to achieve the purpose of making the horizontal scale plate 32 perpendicular to the bottom plate 21. Figure 7 shown.

[0047] In a further preferred embodiment of the present invention, Figure 2 、 Figure 3 and Figure 4 As shown, a sliding groove 26 is provided at one end of the guide plate 22 away from the mounting platform 23, and a locking plate 29 is provided inside the sliding groove 26. The distance between the locking plate 29 and the bottom plate 21 is equal to the thickness of the horizontal scale plate 32. A pull plate 27 is fixedly provided on the end wall of the locking plate 29, and a lifting spring 28 fixedly connected to the guide plate 22 is provided on the outer peripheral wall of the pull plate 27.

[0048] In this embodiment, Figure 2 As shown, when the horizontal scale plate 32 is parallel to the bottom plate 21, as shown in FIG. Figure 3 As shown, the end of the locking plate 29 extends between the two guide plates 22, so that a protrusion is formed on the inner side of one of the guide plates 22. Since the distance between the locking plate 29 and the bottom plate 21 is equal to the thickness of the horizontal scale plate 32, when the horizontal scale plate 32 is tightly attached to the bottom plate 21, the locking plate 29 can clamp the horizontal scale plate 32, so that the horizontal scale plate 32 is fixed. Figure 4 As shown, by setting the lifting spring 28, the locking plate 29 can be inserted into the inside of the guide plate 22. When the position of the horizontal scale plate 32 needs to be adjusted, the pull plate 27 is manually stretched to pull out the locking plate 29, and the horizontal scale plate 32 can be flipped.

[0049] In a further preferred embodiment of the present invention, Figure 5 、 Figure 6 and Figure 8As shown, the connecting hinge 42 includes a first connecting plate 421 and a second connecting plate 422. The first connecting plate 421 and the second connecting plate 422 are both arranged in the shape of a right-angled isosceles triangle, and the hypotenuse is arranged at an angle of forty-five degrees to the side of the horizontal slider 41. The first connecting plate 421 is fixedly connected to the horizontal slider 41, and the second connecting plate 422 is fixedly connected to the longitudinal scale plate 43. The first connecting plate 421 and the second connecting plate 422 are rotatably connected via a shaft 423.

[0050] In this embodiment, the first connecting plate 421 and the second connecting plate 422 are fixedly connected to the horizontal slider 41 and the longitudinal scale plate 43 by screws, and the shaft 423 corresponds to the oblique edges of the first connecting plate 421 and the second connecting plate 422. Therefore, when the second connecting plate 422 is flipped, the angle of the longitudinal scale plate 43 can be adjusted so that the longitudinal scale plate 43 forms a vertical angle with the horizontal scale plate 32, as shown in FIG. Figure 6 As shown, the longitudinal scale plate 43 and the transverse scale plate 32 together form a coordinate system with scales to facilitate determination of the location of the leakage.

[0051] In a further preferred embodiment of the present invention, Figure 2 As shown, a limiting platform 8 is provided at one end of the transverse scale plate 32 away from the fixing plate 31 , and the bottom surface of the limiting platform 8 is flush with the bottom surface of the mounting platform 23 .

[0052] In this embodiment, since the bottom surface of the limit platform 8 is flush with the bottom surface of the mounting platform 23, when the electromagnetic measuring meter is placed close to the ground or wall, the limit platform 8 and the mounting platform 23 can provide better support for the horizontal scale plate 32 and the electromagnetic measuring meter, thereby avoiding the problem of shaking of the electromagnetic measuring meter.

[0053] In a further preferred embodiment of the present invention, Figure 2 As shown, the end wall of the bottom plate 21 is provided with a positioning bracket 9 , and the positioning bracket 9 is fixedly connected to the electromagnetic detection meter 1 .

[0054] In this embodiment, the stability of the electromagnetic measuring meter is further improved by providing the positioning bracket 9 .

[0055] In a further preferred embodiment of the present invention, Figure 8 As shown, the first sliding assembly 6 includes a side plate 61, which is fixedly connected to the end wall of the transverse slider 41. A compression spring 62 is provided on the inner side of the side plate 61, and a friction plate 63 is provided at the end of the compression spring 62. The friction plate 63 is in contact with the transverse scale plate 32.

[0056] In this embodiment, the side plate 61 is provided for installing a compression spring 62 and a friction plate 63. The friction plate 63 contacts the surface of the transverse scale plate 32, so that the longitudinal scale plate 43 has a certain damping when sliding, so as to achieve the purpose of the longitudinal scale plate 43 being able to stop at will, thereby facilitating the adjustment of the longitudinal scale plate 43.

[0057] In a further preferred embodiment of the present invention, Figure 9 As shown, the second sliding assembly 7 includes a top frame 71, which is fixedly connected to the electromagnetic inductor 5. Both ends of the top frame 71 are provided with fixing grooves 72, and a damping plate 73 is provided inside the fixing groove 72. The bottom end of the damping plate 73 is provided with a support spring 74.

[0058] In this embodiment, fixed grooves 72 are provided on both sides of the top frame 71, and the groove walls on both sides of the longitudinal slide groove 44 are inserted into the fixed grooves 72 to achieve the purpose of installing the top frame 71 inside the longitudinal slide groove 44, and the top frame 71 is sleeved on the outer peripheral wall of the electromagnetic sensor 5, so that the electromagnetic sensor 5 is slidably connected to the longitudinal scale plate 43, and the damping plate 73 is brought into contact with the groove wall of the longitudinal slide groove 44 through the support spring 74, so that the top frame 71 has resistance when sliding, so as to realize the arbitrary stopping of the top frame 71 and avoid the problem of the top frame 71 being offset by gravity or other influences.

[0059] The working principle of the above embodiment is as follows: the electrician holds the electromagnetic detection meter 1 and makes the display screen of the electromagnetic detection meter 1 face himself, rotates the longitudinal scale plate 43 along the connecting hinge 42 so that the longitudinal scale plate 43 forms a right angle with the transverse scale plate 32, and rotates the transverse scale plate 32 along the hinge with the fixing plate 31 so that the transverse scale plate 32 and the bottom plate 21 are perpendicular to each other. At this time, the bottom end of the electromagnetic detection meter 1 has a bracket of a certain length, so that the electromagnetic sensor 5 can be close to the ground when the electrician is standing upright, so as to facilitate the determination of the approximate location of the leakage point;

[0060] When detecting a leakage point, the horizontal scale plate 32 is rotated to be perpendicular to the vertical scale plate 43, and the electromagnetic detection table 1 is attached near the leakage point. At this time, the horizontal scale plate 32 and the vertical scale plate 43 form coordinates, and the electromagnetic sensor 5 forms an accurate coordinate point through the sliding vertical scale plate 43 and the second sliding component 7, which can effectively improve the accuracy of leakage detection to facilitate maintenance of the leakage point.

[0061] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
